摘要： In this method for obtaining metals, their compounds, and alloys from mineral raw materials a burden is prepared by mixing a comminuted raw material with additions of chemical elements taken from the chemical composition of the starting raw material, oxidizing roasting is then carried out accompanied by evacuating and utilizing gaseous oxides, and a reduction process proceeds followed by separation of metals and their compounds. According to the invention, in the course of preparing the burden compounds of the above chemical elements containing oxygen are added to the mixture at a ratio of the compounds to the chemical elements ranging from 1:1 to 1:100 and at a total quantity of additions in the burden at least 5%. The oxidizing roasting process proceeds in an oxygen-containing atmosphere at a temperature from 1400.degree. to 1600.degree. C. followed by cooling and comminuting solid oxides obtained. Prior to metallothermy these oxides are mixed with a reducing metal being used at a ratio of the total of oxides of the metals obtained, alloys to the reducing metals ranging between 1:0.3 and 1:0.7. Reduction process proceeds at a temperature 2000.degree. to 2300.degree. C.
